Subject: [PATCH v2 06/13] exfat: remove the unreachable warning for cache miss cases
Date: Thu, 8 Jan 2026 15:49:22 +0800 [thread overview]
Message-ID: <20260108074929.356683-7-chizhiling@163.com> (raw)
In-Reply-To: <20260108074929.356683-1-chizhiling@163.com>
From: Chi Zhiling <chizhiling@kylinos.cn>
The cache_id remains unchanged on a cache miss; its value is always
exactly what was set by cache_init. Therefore, checking this value
again is meaningless.
